This invention relates to hinge connections for members to be pivotallyconnected to other members and is particularly adapted in mounting seatsand covers therefor on water closet hoppers.

The invention consists of novel means for attaching the hinge plates tothe seats and covers, the object being to rigidly secure these plates inposition without the use of screws or similar elements.

This object is attained by the mechanism shown in the accompanyingdrawings.

For the purpose of illustrating the invention, one preferred formthereof is illustrated in the drawings, this form having been found togive satisfactory and reliable results, although it is to be understoodthat the various instrumentalities of which the invention consists canbe variously arranged and organized, and the invention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described except as required by the scope of theappended claims.

Figure 12 represents a horizontal trans verse section showing means formounting the two-part se'at upon the supports without a cover.

Figure 13 represents a vertical transverse section of, a one-part seatand cover showing the end plates provided with hubs extending intosockets in the seat.

Figure .14 represents an elevation of'the inner face of anend plateprovided with a seat engaging stud, and

Figure represents an elevation of the inner face of an end plate used inconnection with the seat when no cover is used.

Similar characters indicate like parts throughout the several figures ofthe .drawmgs.

In the drawings, 10 is a portion of water closet hopper having a flange11 to which posts 12 are securedinthe usual manner by nuts 13 threadedto shanks 14 extending through the flange 11. r I

The upper end ofeach post 12 is preferably curved forwardly and isprovided at its upper end with an opening 15 into which extends acylindrical hub 16 formed upon anend plate 17, each hub being pro videdwith a cylindrical socket 161 at its inner end.

The hubs 16 of the end plates 17 are prevented from being displaced fromthe supports 12 by means to be hereinafter described. g The upper end ofeachplate 17 has a forward extension 18 and on the inner face of eachmember 17 and extension 18 are two cylindrical lugs 19 whichareadaptedto extend into cylindrical holes formed in a rear ward extension 20forming part of acover Each end plate 17 is provided on its inner facewith a semi-annular rib '22, the lower end of which is adapted to abutthe forward side of one of-the posts 12 when the cover is in horizontalposition, as shown in Fig. 4:, while the opposite end of said rib 22 isadapted to abut the rear of said post 12 when the cover 21 is in raisedposition, as indicated in Fig. 5.

In each socket 1600 is a collar 17w surrounding the outer end of acylindrical metal rod 23 which accurately fits a cylindrical hole 23%extending transversely of a rearward extension 24, forming a portion ofa two-part seat 25, open at the front and rear, as shown in Figs. 1 and3. v

Thedistances between the'outer side faces of the extensions 24 is lessthan the distance between the outer side faces of the extension 20, sothat in looking down upon the top of the seat 21 the extensions 24 arenot exposed to view..

Between the two extensions 24 is a tubular member 26 of insulatingmaterial which retains the two extensions 24 properly spaced apart.

Between these two extensions 24 and in front of the tubular member 26 isa tube 27 of the same length as tubular member 26 and through whichextends a metal rod 28, the opposite ends of which are tapered andprovided with right hand threads as at 29.

The inner ends of the metal rods 23 are tapered, as at 30, and incontact before these rods are forced towards each other, while theirouter ends are upset over the outer ends of the collars 17 w which serveas trunnions for the seat 25.

The holes 2300 serve as guides for the rods 23 so that the tapered endsof these rods will always meet accurately within the tubu- 'lar member26, substantially midway of its length.

The holes 2300 are first formed in the extensions 24 and. then the rods23 with the collars or trunnions 17m mounted on the outer ends thereofare forced into these holes 23m under pressure.

At the same time that these rods 23 are being forced inwardly with theirtapered ends 30 contacting, an electric current is passed through therods 23 causing said innor ends 30 thereof to be welded together so thatthe trunnions 179: are permanently secured in position and cannot beseparated from said seat 25. v

Preferably a washer 3000 is positioned between each trunnion 17aa andthe outer side wall of extension 24 to prevent said side wall fromcontacting with any portion of the end plate 17 or support 12.

The threaded ends 29 of the rod 28 are so positioned in the extensions24 of the seat that the inner faces of the extensions 24 will bearfirmly against the opposite ends of the tube 2'T. Y

hen the metal rods 23 have been welded together with the inner walls ofthe extensions 24 bearing against the opposite ends of the tubularmember 26, the separation of said extensions Willbe effectually.prevented and the trunnions 1700 will be rigidly held against thewashers 3000 so that they cannot turn relatively to the rods 23.

lVhen this has been accomplished the two parts of the seat 25 arerigidly held together and cannot spread apart, move inwardly or assumeinclined positions relatively to each other. When the inner ends of therods 23 are thus connected together, it is impossible for thecylindrical trunnions 1702 forming a pivot for the seat 25 to bedisplaced.

One set of lugs 19 oppositely disposed on the end plates 17 have metalrods 19m extending inwardly therefrom into a hole extending transverselyof the extension 20 of the cover 21.

The inner ends of these rods 1900 are tapered and in contact beforepressure is applied to force them toward each other.

hen such pressure is applied and an electric current is passedtherethrough, the tapered ends will be welded together so that it isimpossible to separate them and consequently the hubs 16 of the endplates 17 cannot become dislodged from the cylindrical bearings 15 inthe supports 12.

The hubs 16 form the pivot for the cover 21 to turn on and the trunnions1706 form the pivot for the seat 25 to turn on.

g It will be noted that the axes of the trunnions 17m and hubs 16 arecoincident so that when the seat 25 and cover 21 are, both raised therecan be no movement of one relatively to the other and consequently allchafing is avoided which is a great advantage'as such chafing will-marthe material enveloping the seat 25 and cover 21 and make themunsightly. V 7

There are two distinct operations of weld ing in the assembling of theseat 25 and cover 21 on the supports 12, the first being the weldingtogether of the rods 23 to secure the trunnions 17m to the seat and thenext being to secure the end plates 17 in position by welding togetherthe rods 19% in the cover 21.

' To prevent short circuiting in the rods 23 when the rods 19% are beingwelded together one of the trunnions 17% is surrounded by a collar 31 ofinsulating material and preferably a paper disk 32 is placed between thetrunnion 17m and the washer 3050, as indicated in Fig. 10. I

To further insure against short circuiting it is desirable to have anair space 33 between the outer end of the trunnions 17m and the innerends of the sockets 1629 as shown in Fig. 7.

By this construction theuse ofscrews and similar instrumentalities isdispensed with and the outer faces of the end plates 17 are smooth andunbroken, thus leaving no depressionsin which foreign substances maylodge.

As before stated, the rearward movement of the cover 21 when in itsraised position is limited by the rearward end of the ribs 22 cominginto contact with the posts 12.

By this construction of hinge connection, said hinge connections may besecured to the cover 21 or seat 25-or to both the cover 21 and seat 25after said. cover 21 and seat 25 have been enveloped with-sheets ofcelluloid or other material without any danger of injury thereto.

In some cases, it is desirable to dispense with the cover 21 and pivotthe two-part seat 25 directly upon the posts 12, in which case theupward extensions 18 of the end plates 17 are dispensed with, and an endplate 34 is used, such for instance as that shown in Fig. 15, in whichcase the rods 23 are secured directly to the hubs 34a: of said endplates 34 and lugs 35 are provided which extend into the seat 25.

This construction is shown in Fig. 12.

In this particular construction just described thehubs 34m extend intothe openings 15 in the posts 12 and each plate 34 is provided with stopshoulders 22a; to coact with posts 12 to limit the movement of the seatin either direction. i

In some cases headed collars 36 are disposed in the outer face of theextensions 24 as shown in Fig. 13, the outer ends of these collarsextending slightly beyond the outer faces of the extensions 24 intocontact with the inner faces of the supports '12, thereby leaving aslight space between the inner faces of the posts 12 and the outer facesof the extensions124. i V

In this construction the end plates 17 are secured in position bywelding together the rods 19m in the cover and said end plates 17 havestuds 37 extending therefrom through the posts 12 andinto the collars36.

In the several constructions shown and described, all rubbing againstthe outer face of the extension 24 is obviated when the seat 25 israised or lowered.

This is of some consequence as the seat is usually covered withcelluloid or similar material and if chafed becomes unsightly.

In some cases the trunnings 1750 may be secured to the seat by a hollowrod 38 extending through seat 25 and trunnions 17m and upset at itsopposite ends, as shown in Fig. 11.

By mounting the seat and cover on a water closet hopper by such hingeconnections as herein shown and described, a perfectly sanitaryconstruction is provided which has great strength and the elements arepermanently retained in position. a

By this construction the use of all screws and similar instrumentalitiesis entirely disof the hinge connections to getvout of commission.

The construction herein shown and described is particularly adapted foruse in rear.

Thestop rib 22 surroundsand .is slightly separated from the peripheryofthe semiannular ends39 :of the posts 12.

The end plates 17 with the rib 22 hide from View the greater part ofthe. posts 12 when the cover 21 is either in raised or loweredposition.-- v
